"Master, you'll be summoned in 5 seconds, be ready,"
Nervous yet expectant, I waited for the beginning of my new destiny.
------------------------
In a place within space where time, reality, fiction, life, death, start, and end cease to have meaning, there lies a library so immense that a galaxy could fit within one of its books, and simultaneously so small that it could fit in the pocket of a human. It defies logic and doesn't seek any, it simply exists.
Within this library resides a young man, unconscious. Despite his enormous mental and soul strength, it's not enough to exist in this space. As the new owner of this library, he must adapt to live here. The library itself aids its owner in this adaptation. How long will it take? It's unknown; after all, time doesn't exist here.
While all of this was unfolding, the concepts of the library and the young man intertwined, adjusting to one another. The library introduced the concept of time, and the young man adapted to living without it. In a span ranging from a second to "now" (an undefined span of time that will eventually arrive), time was formed.
As the library created an environment for the young man to breathe and nourish himself, he adapted to living without it. With the concept of time, he learned that a mere year had passed, though to him, but for the whole of things, was a speck of dust.
As the library connected to every part of the being named Daniel, he began to grasp the library's concepts. Yet, it would take him some more time—10,567 years to be exact. To the grand scheme of things, two specks of dust.
Daniel didn't comprehend the library with his consciousness or his brain. He understood it with his soul. The knowledge now belonged to him and only him. Once he had gained enough understanding to fulfill his role as a librarian, Daniel opened his eyes.
"This destiny is more significant than I thought. This mission is fundamental for the balance of the universes. I'm sorry, Ako, it seems we won't meet again—" Before "Daniel" could finish his words, commands echoed in his mind, and a blue screen appeared.
[System rebooting--…]
[Error] [Retrying…] … [Retrying] [Successful, system initiated]
[Executing "humanity Daniel" backup]
[Execution error, alteration by unknown entity]
[Requirements fulfilled, unlocking title]
[New Title: <Trojan> Affects system and executes backup]
["Humanity Daniel" backup completed]
After a few seconds, Daniel returned.
"Hello? Clarion? Did it work?" Daniel asked, his demeanor strikingly different from before.
"It worked, Master! We did it!"
"The plan worked... I almost lost myself... again."
During the three days before his summoning, Daniel not only enjoyed his vacation but also divided his consciousness to program commands into his system in case of unforeseen situations.
Since the previous incident where Daniel almost lost his emotions, a deep fear and anxiety had taken root. He worried about forgetting who he was in the pursuit of power.
That's why he developed several plans in case he'd get carried away by power or encounter a being so powerful that it sought to control him.
The plans ranged from trapping him in an infinite loop of his most important memories to triggering his remembrance of self.
The previously executed backup or hiding his "essence" deep within his soul to find a chance to return.
The last plan was the most challenging and dangerous. Superior beings could see and read souls. If he didn't hide well enough, they could find him. But if he hid too deep, he'd be lost, and only a miracle would bring him back to himself.
"Clarion, execute the system and show me its updates."
"Yes, Master."
While Daniel was unconsciously adapting, Clarion incorporated all the information entering Daniel's soul. Simultaneously, Clarion evolved, consuming the raw destiny energy generated by the library. The system was now upgraded to the Omniversal level.

"Now I understand why everyone hunts system users, they're extremely overpowered. Or... am I the overpowered one?"
"Appreciate me more, Master. I put a lot of effort into configuring the system," Clarion said with a grin from ear to ear, clearly proud of her results.
"You can ask me for anything you want, Clarion," Daniel said gratefully. For him, it had been less than a week and his life had already changed so much, all thanks to Clarion.
"How much time has passed, Clarion?"
"Since the concept of time was created, 10,567 years and 215 days have elapsed, Master."
"I see, it seems I lost everything in my pursuit of power."
"Don't worry, Master. While I was unconscious, I observed your homeworld; only about 11 seconds have passed there. Time flows differently in this place."
"Even though I now possess so much knowledge, I still feel somewhat clumsy. Thank you, Clarion."
"That's not true, Master. You just need to get used to it."
"I was fortunate with the time difference; perhaps the protagonist title is taking effect."
"You're right, Master. Titles and abilities have also been unlocked."
"Show me the descriptions of the titles, Clarion."
<Title: Trojan>
<Description: There's nothing to see here, just a decent citizen trying to take control of the world.
Like the Trojan horse, you will infiltrate as a seemingly harmless gift and then seize control from within. With this title, the will of the world, gods, or primordial beings won't perceive your existence upon entering a new world.>
<Virus>
<Description: It's just a cold, it'll go away in a while; Status: Dead
You'll be able to infect any concept you wish and take control of it.>
<Spectator>
<Description: Quiet, everyone! My favorite novel has started.
You'll be able to coexist and observe firsthand how stories unfold, from NPC to spectator, from spectator to supporting character, from supporting character to protagonist.>
"Wow, it's more powerful than I imagined."
Daniel raised his hand, and out of nowhere, a sheet of paper with strange symbols appeared. If you could understand the symbols, it would read "Life of Daniel Ashikaga."
"Let's see... Clarion, analyze the story of my life with me."
"Yes, Master. I'm curious too."
....
"Oh, so that's how it happened..."
"I thought we were going to uncover a universe secret, Master."
The story is brief; in Daniel's world, many human-level stories unfold, like comedy, romance, etc.
There's something that characterizes Daniel: he enjoys gossip.
He isn't someone who spreads it or intentionally seeks it out, but he enjoys knowing interesting things about others' lives.
What happened was that Daniel became intrigued by the stories of the protagonists in his world. That's when the world categorized him as an NPC, a supporting character.
The next situation occurred when Daniel joined the volleyball club and became Ako's boyfriend.
He did what an NPC shouldn't do: interfered with the main plot.
The world's will didn't see him as a threat; after all, they were simple plots with small destinies.
However, without realizing it, he slowly started usurping the destinies of those plots.
Going in and out of the bench during matches, scoring decisive points. He dated the main protagonist, causing secondary protagonists to develop feelings for him, becoming the protagonist.
If he had gained the spectator ability before, he now also gained the unique virus ability.
After all, even a poorly cared for small cut on a finger could lead to amputation of the hand.
It all culminated when a human with a destiny that didn't belong to him caught the attention of a small system fairy.
At that moment, the minor flu turned into the worst disease one could contract, and that's when he earned the title of Trojan.
-----------------
Note: If you mention any items for the system's store or gacha, I would greatly appreciate it.
I added the Omnitrix, but it's only to highlight that he has access to all kinds of universes. I'm not sure about incorporating it from cartoons, movies, or video games. For now, it's more focused on anime, manga, manhwas, or manhuas.
